With a sentence like the one above you are unlikely to communicate anything meaningful about a graph, table or chart. If there was a rise or a fall, then you need to state precisely what it was that rose and what it was that fell – What is the subject?

For example:

The divorce rate in Americarose steadily, while the divorce rate in Indonesiafell dramatically.

Here there are 2 subjects:

the divorce rate in America

the divorce rate in Indonesia

Some of you will complain about the repetition in this sentence (‘the divorce rate‘). However, it’s better to repeat words and phrases and communicate something meaningful than to avoid repetition and communicate nothing.
